We live in an exciting time.

We live in an era in which art can be expressed online, for the world to see, in a marketplace that will actually reward talent. Sure, this process is highly subjective and undefinable, but the success Colbie Caillat had in 2007 is nothing short of an Internet dream.

The top unsigned artist on MySpace.com for much of the year, Caillat comes in at No. 15 on my list of 2007's best songs with "Bubbly," a song that is at once highly clever and potentially, mind-numbingly annoying.

I don't say that to degrade the daughter of Ken Caillat, who co-produced a pair of huge Fleetwood Mac albums in the 1970s. However, Bubbly was quite the ubiquitous song in 2007. While it got its legs on the Web, it's been done and overdone on mainstream radio.

Nevertheless, this single and other tunes off her CD, CoCo, prove she's got some potential as a songwriter. If I'm forced to make a choice between Caillat and Sara Bareilles, who I featured at No. 16, I'd take Bareilles on any number of fronts.

Bareilles' songwriting, vocals, musicianship and potential dwarf Caillat's. However, "Bubbly" was 10 times the hit that "Love Song" was, and for good reason. It's really a perfect little sweet pop song, and if Caillat can write some more of those, she'll be around a long, long time.
